Locking device

A locking device comprising:

• a casing;
• a cover fastened to said casing and forming a striker guide recess cooperating with said casing;
• a latch plate for locking a striker, said latch plate being rotatably supported by said casing and said cover;
• a locking plate being rotatable supported by said casing and said cover, said locking plate locking said latch plate in its turn, thereby to ensure a locking of said striker by said latch plate;
• locking-state removal means for removing the locking of said striker by said latch plate by turning said locking plate;
• and
• a striker pressing plate, rotatable supported by said cover for pressing said striker against said latch plate in a state that said latch plate is locked in its turn,
• wherein said striker pressing plate has an engaging protrusion and said cover has a bore engaged with said engaging protrusion so that said striker pressing plate is directly supported by said cover.

A locking device comprising:

• a casing;
• a cover fastened to said casing and forming a striker guide recess cooperating with said casing;
• a latch plate for locking a striker, said latch plate being rotatable supported by said casing and said cover;
• a locking plate being rotatably supported by said casing and said cover, said locking plate locking said latch plate in its turn, thereby to ensure a locking of said striker by said latch plate;
• locking-state removal means for removing the locking of said striker by said latch plate by turning said locking plate;
• and
• a striker pressing plate, rotatable supported by said cover for pressing said striker against said latch plate in a state that said latch plate is locked in its turn,
• wherein said cover has a guide slit and said striker pressing plate has an engaging shaft inserted into and being movable along said guide slit.

A locking device comprising:

• a casing;
• a cover fastened to said casing and forming a striker guide recess cooperating with said casing;
• a latch plate for locking a striker, said latch plate being rotatably supported by said casing and said covery;
• a locking plate being rotatably supported by said casing and said cover, said locking plate locking said latch plate in its turn, thereby to ensure a locking of said striker by said latch plate;
• locking-state removal means for removing the locking of said striker by said latch plate by turning said locking plate;
• a striker pressing plate, rotatable supported by said cover for pressing said striker against said latch plate in a state that said latch plate is locked in its turn;
• and
• a plate spring fixed on said cover at a first end thereof, said striker pressing plate having a spring receiving part for receiving a second end of said plate spring.

A locking device for use in combination with a striker, comprising:

• a casing and a cover including a striker guide recess;
• a latch plate rotatably supported between said casing and said cover and biased toward a first position;
• said latch plate further comprising a striker receiving recess and a first engaging part which overlaps said striker guide recess when said first engaging part is in said first position;
• a locking plate rotatably supported between said casing and said cover, said locking plate including a second engaging part and said locking plate being in a first position;
• a striker pressing plate, rotatably supported between said casing and said cover;
• a lock removal rod rotatably attached to said locking plate;
• and
• a spring coupling said latch plate and said locking plate;
• wherein sad striker is adapted to enter said striker guide recess to contact said first engaging part and rotate said latch plate to a second position wherein said striker receiving recess prevents movement of the striker out of said striker guide recess,
• wherein a rotation of said latch plate to said second position rotates said striker pressing plate and said locking plate into a position wherein said striker pressing plate, said locking plate, and said latch plate are all in a locked state,
• wherein a predetermined movement of said lock removal rod rotates said locking plate and terminates said locked state, thereby allowing said latch plate to assume said first position and allowing egress of the striker from said striker guide recess, and wherein said spring biases each of said latch plate and said locking plate in an opening direction.
